Everybody loves the way eggs slide off of Teflon pans. Indeed, the carbon-fluorine bond at the heart of Teflon cookware is so helpful we also use it in products from clothing to blood substitutes.

But the very strength of the C-F bond also gives it greenhouse gas effects. In the journal Science, researchers report a catalyst that breaks the C-F bond and converts it to a carbon-hydrogen bond, rendering it harmless to the environment.

(Brandeis University) Everybody loves the way eggs slide off of Teflon pans. Indeed, the carbon-fluorine bond at the heart of Teflon cookware is so helpful we also use it in products from clothing to blood substitutes.

But the very strength of the C-F bond also gives it greenhouse gas effects. In Science this week, Brandeis researchers report a catalyst that breaks the C-F bond and converts it to a carbon-hydrogen bond, rendering it harmless to the environment.
